Repetitive activities can lead to a painful inflammation of muscles, tendons and periosteum of the tibia. This condition is called medial tibial stress syndrome, or shin splints. An overuse injury, shin splints are caused by over-stressing the shinbone and the connective tissues that attach the muscles to the bone.

Stretching your leg muscles before strenuous activity can help to avoid shin splints, but even the most staunch stretcher may fall victim to the condition. In very severe cases, surgery may be necessary to correct the tissue damage around the lower leg bone.

Hiking can provide a relaxing outdoor experience, but if you overdo it, you may experience soreness. A sore calf from hiking could result from trying to do too much, too quickly. The soreness is usually a sign of your body adjusting to the new activity.

Broiling and grilling do not have many differences. In fact, an oven broiler is essentially a grill flipped upside down. Although you don't get the charcoal flavor that can be provided by some types of grills, broiling is a much easier method of cooking meat and can be done without any extra equipment.

There is little extra space around the spinal cord in the thoracic spine. Hence, a herniated disc in the thoracic spine can be serious. Sometimes, the first sign of the herniated disc is paralysis below the waist. Fortunately, a herniated disc in the thoracic spine is not as common as in the lumbar spine.

Rhomboid muscles in upper back connect the inner edges of the shoulder blades to the spine.

An abdominal muscle tear, or strain, can occur from overstretching or overusing the muscle and is a common injury among tennis players. A violent, poorly performed movement of the trunk can also strain the abdominal muscles, suggests the Better Health Channel.

Experiencing back pain or nausea after eating a meal is usually an indication of a gastrointestinal problem. Several gastrointestinal conditions can cause nausea and abdominal pain that radiates to locations in the back. While some conditions may be mild or short termed, others may be severe, chronic and serious.

While lower back injuries are common among golfers, the rhomboid muscle located in the upper back can also be injured during golf. The triangular-shaped rhomboid muscle lies between the shoulder blades and connects the inside edges of the blades to the spine.

Chiropractors treat problems affecting your muscles, skeletal structure and nervous system. This type of therapy does not involve drugs or surgery, only the physical manipulation -- adjustment or realignment -- of your spine and neck by hand.

Low-carbohydrate diets can lead to weight loss, but they are not without risk. If you cut your carb intake too low or you eliminate certain food choices completely, you may find yourself struggling with muscle aches, pains or cramps. Tweaking your diet to address the reasons behind aching and cramping can help.

As common as they are, muscle cramps are something of a medical mystery -- they can affect anyone at any time, and it can be difficult to pinpoint exactly why they develop.
